There are two hex head bolt sizes of the subject's t-top bolts that I have seen offered by vendors at Spring Carlisle. Both sizes listed the same years (68-75?). I happen to have one of the larger ones and 3 of the smaller sizes on my 70. Does anyone know which size is correct for which years? I can look up the sizes tomorrow if it helps anyone out.

Re: 1970 T-top Hollow Bolts with Rubber Bumpers

Your '70 originally used the smaller sized rubber-bumpered bolt. This early style bolt was never available from GM as a service part; it came only as part of the lock assembly. It is, however, currently available in reproduction. The 76+ bolt with the larger head was serviced by GM under part number 359611. It is sometimes used by folks as a service replacement for 68-75 models, although it was never catalogued by GM for use in those applications. As far as I know, it is still available.In Appreciation of John Hinckley -
